A solid circular disk has a mass of 1.2 kg and a radius of 0.16 m. Each of three identical thin rods has a mass of 0.15 kg. The rods are attached perpendicularly to the plane of the disk at its outer edge to form a three legged stool. Find themoment of inertia of the stool with respect to an axis that isperpendicular to the plane of the disk at its center.
(Hint:when considering the moment of inertia of each rod, note that allof the mass of each rod is located at the same perpendiculardistance from the axis)

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.

i believe the answer is a hope it and is correct
